I have created a DVD containing Ubuntu 14.04 and have successfully run 14.04 from it. I have taken the option to install 14.04 as a dual boot with Windows XP.
The installation appeared to go smoothly and I have two extra partitions on my windows 'C' drive, /dev/sda6 and /dev/sda7.
When I switch on the laptop I get the dual boot option. The Windows XP boot works ok (I'm using it now), but the Ubuntu 14.04 boot option runs so far, then terminates with the message:
(initramfs) unable to find a medium containing a live file system.
Any help will be gratefully accepted!
